Uplink: 145.945 MHz UI digipeater
Digi Callsign: KE6QMD

The NO-45 digipeater remains on. User are requested NOT to use the Bulletin Board. When the Bulletin Board is used it effectively "locks out" ground access to the spacecraft CPU.

Everyone is welcome to use the digipeating/APRS features of Sapphire, callsign KE6QMD, as per the user service agreement located at

There will be occasional dropouts caused by the CW beacon, and users are advised to expect extra packet chatter during West Coast (USA) passes, as some schools are using Sapphire for operations training.

Student built Sapphire was launched through the U.S. Naval Academy Satellite program. Its primary missions are sensor experiments, a camera, and voice synthesizer. For more information, visit the Sapphire web site at


The following satellites are in orbit but are semi-operational at this time.

Catalog number: 25509
Downlink 437.910 MHz FM 9600 Baud FSK
Launched October 24, 1998 by a Delta 2 rocket from Cape Canaveral in Florida

The satellite is not currently available for uplink transmissions and image and transponder recovery efforts have been unsuccessful.

SEDSAT-1 signifies Students for the Exploration and Development of Space (satellite number one).

SedSat-1 has downlinked months worth of telemetry data on the performance of its electrical power system parameters. The Nickel Metal Hydride batteries on the spacecraft were experimental and experienced some abuse due to a power negative situation. This information has provided NASA with useful information. With the exception of the imaging system and the use of the transponders, SedSat-1 has been judged a success.

For more information on SedSat-1 visit the satellite web site at

ANS has no further information.

AO-49 (SAFIR-M) is a German amateur radio payload onboard the small German scientific satellite "RUBIN-2".

AO-49 was built by the German amateur radio association "AATiS e.V." (German acronym for "Arbeitskreis Amateurfunk und Telekommunikation in der Schule", which means: 'working group for amateur radio and telecommunications in schools'). AO-49 is designed as a "store and broadcast" system for APRS based messages, dedicated for the use of schools in combination with the existing WX-Net and planned buoy experiments in Germany.

No transmissions detected since the 1st of February 2003! It appears AO-49 is not properly aligned to illuminate the solar panels. This should end soon. Due to its orbit, AO-49 will be in a phase without eclipses until 13Feb03.

Martin DG8UAU has written a small software program "SAFIR-M Decoder" to allow decoding of the received DATA0 frames. It is available at in the section Aktuelles.

Details on AO-49 (SAFIR-M) can be found at
Information about AATiS e.V. is available at
